cat $SIGMASTAR_SDK_PATH/build/config | grep -E "BOARD_NAME|CHIP|UBOOT_CONFIG" 4.1 Clean Any Previous Builds cd $SIGMASTAR_SDK_PATH make clean # or ./build/clean_all.sh 4.2 Full SDK Build The most common entry point is the top-level Makefile: sigmastar sdk install

cd ~/sigmastar_workspace tar --exclude='build/.ccache' --exclude='kernel/.git' \ -cjf Sigmastar_SDK_ready_to_use.tar.bz2 Sigmastar_SSD222_SDK/ Include a README with environment setup instructions. Pitfall 1: Hardcoded Absolute Paths Some SigmaStar build scripts hardcode paths like /home/user/sdk . If your username differs, you must: ssd222_evb_defconfig

nano ~/sigmastar_workspace/setup_sdk_env.sh Add the following (adjust path to your actual extracted folder): By following this guide—preparing a clean Ubuntu 20

docker build -t sigmastar-builder . docker run -it --rm sigmastar-builder make all The SigmaStar SDK install process is not insurmountable, but it demands respect for legacy toolchains, fixed paths, and vendor-specific build steps. By following this guide—preparing a clean Ubuntu 20.04 host, extracting carefully, configuring per your board, and methodically building each component—you will move from a raw SDK tarball to a booting SigmaStar device.
